CD Error Correction Tests

In the following tests we check the drive's behavior when reading
scratched / defective audio discs. The test discs used were the ABEX series
from ALMEDIO.

The performance with the 721R test disc is satisfactory. The loudness level
is fairly low with tha maximum at -26.4 dB(A). No
samples
were
skipped and the total score of 76 .4 is about average. The drive cannot return
C2 error pointers, and so there is no score posted for C2Accuracy.

- ABEX TCD-726

The Abex TCD-726 test disc is much easier for drives in general to read. The ASUS DRW-1604P drive reached 92.6 score (out of 100), which is very good.

- CD-Check Audio Test Disc

The CD-Check Test Disc is a very useful tool for evaluating the Sound Reproduction
/ Error correction capabilities of a CD player. The disc offers a signal combination
with disc error patterns to rate the drive's abilities to read music and reproduce
it completely. Five tracks on the disc contain a sequence of progressively
more difficult tests. These tracks are referred to as Check Level-1 through
Check Level-5.

The
tracks are being reproduced through a software multimedia player (i.e.
Windows Media Player). Each level is considered as passed, if the tone
is smooth, continuous without interruptions, skipping or looping. The higher
the Check Level passed, the more reliable the sound reproduction
of the tested drive.

have seen from a PC drive!
